Abstract (en)

[origin: WO9945251A1] A multi-shaft reheat turbine mechnism includes multiple turbines mounted on respective compressor shafts, and catalytic reactors feeding respective ones of the turbines. Fuel is introduced into a low pressure compressor, whereby there is no need to pressurize the fuel. The compressor side of the mechanism emits a compressed air/fuel flow, portions of which are combusted in respective ones of the catalytic reactors. The air/fuel flow traveling from the compressor side to the turbine side passes through a regenerator in heat exchanging relationship with exhaust gas from a low pressure turbine.
